this is the jacket my nintendo friend wore at all the major competitions he ran. the mario tie was a sample made for a promotion that never happened. the vase was from the 1992 nintendo military challenge that the winner never claimed.
there is also a list of nintendo competitions, im quessing there's a couple here no ones heard of. he also gave me a bunch of nintendo competition video tapes(campus challenge, powerfest, nwc, etc). as far as prices go he told me he wanted $1000 for the jacket (i know). as far as the other items its up to me to see what they might be worth.
he also showed me a large gold colored brass or bronze mario statue that was given to special people at nintendo(pics soon).
